Target

  • Function
    Acts as a ligand for Notch receptors. Blocks the differentiation of progenitor cells into the B-cell lineage while promoting the emergence of a population of cells with the characteristics of a T-cell/NK-cell precursor.
  • Tissue specificity
    Expressed in heart and pancreas, with lower expression in brain and muscle and almost no expression in placenta, lung, liver and kidney.
  • Sequence similarities
    Contains 1 DSL domain.
    Contains 8 EGF-like domains.
  • Post-translational
    modifications
    Ubiquitinated by MIB (MIB1 or MIB2), leading to its endocytosis and subsequent degradation.
  • Cellular localization
    Membrane.

Images

  • ab10554 staining DLL1 in U2OS cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% paraformaldehyde, permeabilized with 0.3% Triton X-100 in PBS and blocked with 4% BSA for 1 hour. Samples were incubated with primary antibody for 1 hour at room temperature. DAPI used to stain nuclei

  • ab10554 staining DLL1 in Mouse embryonic kidney tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Samples were incubated with primary antibody (2ug/ml) for 1.5 hours at room temperature. A peroxidase-conjugated polyclonal was used as the secondary antibody. Nuclei stained purple with hematoxylin.

  • ICC/IF image of ab10554 stained MCF7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab10554, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.



  • Predicted band size : 78 kDa

    Western blot using Delta 1 antibody (ab10554) at 1/500 tested on the following tissue lysates:

    Lane 1: Mouse Heart
    Lane 2: Mouse Pancreas
    Lane 3: Mouse Brain
    Lane 4: Rat Heart
    Lane 5: Rat Pancreas
    Lane 6: Rat Brain

    Secondary ab: Goat anti-rabbit IgG ab6721 (1/5000)
    Exposure time: 1 minute
    Expected molecular weight: 77kDa
    Cell lysates at 20µg per lane.

    NB: This image shows that is was not possible to detect Delta 1 immunoreactivity by WB in the lysates tested. However little is known about Delta 1 expression and it is likely to be developmentally regulated with low expression/abundance making it difficult to detect in whole tissue homogenates. In favour of Delta 1 antibody (ab10554), the staining on the WB shows very low background and little cross reactivity in whole homogenates.

Unfortunately it is not possible for us to sell the pre-immune serum of our rabbits.
I am sorry that on this occasion I could not be of more help.
